Idea
Dynamic user representation platform enhancing scenario-specific personalization and scalability for large-scale industrial applications.
Research Paper
Core Innovation
This paper introduces Query-as-Anchor, shifting from static to dynamic, query-aware user embeddings using large language models. It leverages a large-scale multi-modal pre-training dataset and a novel dual-tower architecture with contrastive-autoregressive optimization. Cluster-based soft prompt tuning aligns representations with scenario-specific modalities, enabling efficient, scalable deployment.
Why It Matters
Static user embeddings often fail to capture diverse, task-specific needs across scenarios, limiting personalization and accuracy. This approach improves user understanding by adapting representations dynamically to queries and scenarios, reducing noise from multi-source data. It scales efficiently for large enterprises, enabling better decision-making and user engagement.
